Abstract
1470101 Valves DANFOSS AS 15 March 1974 [17 March 1973] 11691/74 Heading F2V [Also in Division G3] A pneumatic pressure regulator device for a ventilating or air conditioning system, has a cup-shaped valve element 39 slidably mounted on a vertical spindle 33 and co-operable with seating 36. In use, air entering pipe 12 lifts the element off its seating against the action its weight to permit some of the air to be exhausted via gap 42 and thereby establish a substantially constant pressure P 2 within the element. This pressure is communicated through ports 46 and passage 44 with a restrictor 54. The downstream side of the latter communicates with a port 51 for connection to a control pressure pipe and with ports 52, 53 for connection to the actuators of respective air-flow control elements of the system. A filter 30 is clamped between casing parts 25, 27 by stud 34 and nut 35. A fixing bracket 56 is provided.
